Need The Perfect Gameplan

I have 3 champions in my roster; Volibear, Warwick, and Nasus. I need to know the right strategy, the right steps, and the right game plan for each of them.

For starters, I pick Warwick as the jungler, and started attacking the frog first, and I don't know what to do next.

Nasus's Siphoning Strike is a great way to build my attack power, but something it's not high enough to get enemy kills.

And for Volibear, I just wing it and attack every minion as I can. However, some enemies attacked me and I try to escape, but I kept getting defeated.

I try each technique I can find, but no such luck. Sometimes I think I overextend too many times, and I keep losing. Give me some advice, some tips, some way I can improve my gameplay. Please, help me out. I feel like that I maybe go on tilt, and I HATE BEING ON TILT! HELP ME OUT SOMEBODY! I FEEL LIKE I'M GOING TO SCREAM MY LUNGS OUT AND GO ABSOLUTELY BERSERK AND PRACTICALLY DESTROY, TEAR APART, AND COMPLETELY KILL EVERYTHING IN MY PATH IN A MOST UNCONTROLLABLE AND SAVAGE RAGE IN MY LIFE IF I DON'T GET ANY HELP ANYTHING SOON!! HELP ME, FOR ******* SAKE! HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
